Also consider setting up [code playgrounds][code-playgrounds]. * If your organization uses code repositories, [set up linkifiers](/help/add-a-custom-linkifier) to make it easy to link to issues (e.g. just by typing #1234 for issue 1234). * [Add custom emoji](/help/custom-emoji), including your organization's logo.
